Apple builds SIM into iPad Air 2

SIM WITHIN: The iPad Air 2 with cellular connectivity features a built-in ‘Apple SIM’

Buyers of the iPad Air 2 will be the first to use a new Apple SIM that comes preinstalled in the Wi-Fi+Cellular version of the tablet and looks set to be the first implementation of a “SIM Within” patent published in November 2011.

“Conventionally, user equipment is provided with a Subscriber Identity Module (SIM) card,” the patent explains. “The SIM card includes security information such as private key information that can be used in authenticating user equipment to a cellular network.

“It may not always be desirable to require the use of SIM cards. For example, the need to include a SIM card slot in user devices tends to make the devices bulky and add cost. It also necessitates management of SIM card inventories and distribution by the manufacturer or service provider.

“A user might also want to purchase wireless services even when the user is not able to easily obtain a SIM card. It would therefore be desirable to be able to provide improved ways in which to provide users with the ability to purchase and use wireless network services.”

For buyers of the iPad Air 2, Apple explains, “the Apple SIM gives you the flexibility to choose from a variety of short-term plans from select carriers in the US and UK right on your iPad. So whenever you need it, you can choose the plan that works best for you — with no long-term commitments. And when you travel, you may also be able to choose a data plan from a local carrier for the duration of your trip.”

AT&T, Sprint and T-Mobile in the US are supporting the service at launch along with UK carrier EE.
